Domänenanforderungen

Domänenanforderungen, often translated as domain requirements, represent the essential needs and functionalities that a software system must fulfill within its specific operational context or business domain. These requirements define what the system needs to do to solve a particular problem or support a specific business process. They are distinct from system requirements, which focus on the technical implementation details of the software.

Gathering and documenting domain requirements is a crucial early step in the software development lifecycle. This process involves close collaboration between stakeholders, such as end-users, business analysts, and domain experts, to ensure a comprehensive understanding of the problem space. The focus is on the "what" – what capabilities are needed, what data must be managed, and what processes must be supported – rather than the "how" – how these functionalities will be technically realized.

Common categories of domain requirements include functional requirements, which describe the specific actions the system must perform, and non-functional requirements, which outline the quality attributes like performance, security, and usability. Examples might include the need for a system to process customer orders, generate financial reports, or manage inventory levels. By clearly defining domain requirements, development teams can ensure that the final product effectively addresses the intended business needs and delivers value to its users. Misinterpretation or omission of domain requirements can lead to significant rework and project failure.
